Detailed description of the invention
For further illustrating each embodiment, the present invention is provided with accompanying drawing.These accompanying drawings are the invention discloses content one
Point, it is mainly in order to illustrate embodiment, and the associated description of description can be coordinated to explain the operation principles of embodiment.Coordinate ginseng
Examining these contents, those of ordinary skill in the art will be understood that other possible embodiments and advantages of the present invention.In figure
Assembly be not necessarily to scale, and similar element numbers is conventionally used to indicate similar assembly.
In conjunction with the drawings and specific embodiments, the present invention is further described.
This description is sayed it " lens have positive refractive index (or negative refractive index) ", refers to that described lens are with Gauss light
The refractive index on optical axis that theory calculates is for just (or being negative).This image side surface, thing side are defined as imaging light to be passed through
Scope, wherein imaging light includes chief ray (chief ray) Lc and rim ray (marginal ray) Lm, such as Fig. 1
Shown in, I is optical axis and this lens are radially symmetrical with this optical axis I for axis of symmetry, and light is by the region on optical axis
For optical axis near zone A, the region that rim ray passes through is circumference near zone C, additionally, these lens also comprise an extension E
(i.e. circumference near zone C region radially outward), is loaded in an optical imaging lens with for this battery of lens, preferably becomes
As light can't be by this extension E, but the structure of this extension E and shape are not limited to this, with purgation embodiment for asking
The graphic extension succinctly all eliminating part.In more detail, it is determined that face shape or optical axis near zone, circumference near zone,
Or the method for the scope in multiple region is as follows:
As it is shown in figure 1, it is lens sectional views radially.See it with this sectional view, judge the model of aforementioned areas
When enclosing, defining a central point is an intersection point with optical axis on this lens surface, and a transfer point is on this lens surface
A bit, and vertical with optical axis by a tangent line of this point.If there being a plurality of transfer point radially outward, then it is sequentially first turn
Change a little, the second transfer point, and on effectively half effect footpath, the transfer point the most farthest away from optical axis is N transfer point.Central point and
In the range of optical axis near zone between one transfer point, N transfer point region radially outward is circumference near zone, middle
Different regions can be distinguished according to each transfer point.Additionally, effective radius be rim ray Lm with in lens surface intersection to optical axis I
Vertical dimension.
As in figure 2 it is shown, the shape in this region concavo-convex be with parallel through the light (or light extension line) in this region and light
The intersection point of axle determines (light focus decision procedure) in image side or thing side.For example, after light is by this region, light
Can focus on towards image side, with the Focus Club position of optical axis in image side, such as R point in Fig. 2, then this region is convex surface part.Otherwise, if light
Behind this certain region, light can dissipate, and its extension line and focus M point in thing side, such as Fig. 2 of optical axis, then this region is
Concave part, so central point is to being convex surface part between the first transfer point, the first transfer point region radially outward is concave part；By
Fig. 2 understands, and this transfer point is i.e. the separation that convex surface part turns concave part, therefore this region of definable and this region radially adjacent
The region of inner side, for boundary, there is different face shapes with this transfer point.If it addition, the face shape judgement of optical axis near zone can
According to the judgment mode of skill usual in this field, (refer to paraxial radius of curvature, the lens being often referred in optical software with R value
R value on data base (lens data)) positive negative judgement is concavo-convex.For thing side, when R value is timing, it is determined that for convex surface part,
When R value is for time negative, it is determined that for concave part；For image side surface, when R value is timing, it is determined that for concave part, when R value is for bearing, sentence
Being set to convex surface part, it is concavo-convex identical with light focus decision procedure that the method determines.
If without transfer point on this lens surface, this optical axis near zone is defined as the 0～50% of effective radius, near circumference
Region is defined as the 50～100% of effective radius.
Fig. 3 is that the surface, lens image side of the first example only has the first transfer point on effective radius, then the firstth district is light
Axle near zone, the secondth district is circumference near zone.The R value of this lens image side surface is just, therefore judges that optical axis near zone has
One concave part；The face shape of circumference near zone is different with the inside region being radially close to this region.That is, circumference near zone and
The face shape of optical axis near zone is different；This circumference near zone has a convex surface part.
Fig. 4 is that the lens thing side surface of the second example has first and second transfer point, then the firstth district on effective radius
For optical axis near zone, the 3rd district is circumference near zone.The R value of this lens thing side is just, therefore judges optical axis near zone
For convex surface part；Region (the secondth district) between the first transfer point and the second transfer point has a concave part, circumference near zone the (the 3rd
District) there is a convex surface part.
Fig. 5 be the lens thing side surface of the 3rd example on effective radius without transfer point, now with effective radius 0%～
50% is optical axis near zone, and 50%～100% is circumference near zone.Owing to the R value of optical axis near zone is just, so thing
Side has a convex surface part at optical axis near zone；And without transfer point between circumference near zone and optical axis near zone, therefore circumference
Near zone has a convex surface part.
The optical imaging lens of the present invention, is a tight shot, and is sequentially to be arranged along an optical axis by from thing side to image side
One of the first lens, one second lens, one the 3rd lens, one the 4th lens, the 5th lens, the 6th lens and optical filter institute structure
Become, each lens all have refractive index and have a thing side towards thing side and making imaging light pass through and towards image side and
Make the image side surface that imaging light passes through.The optical imaging lens of the present invention is by designing the detail characteristic of each lens, and can provide
Shorter optical imaging lens length and good optical property.
The characteristic of aforementioned each eyeglass must consider again optical characteristics and the lens length of optical imaging lens, for example: light
Circle position is arranged on the thing side of the first lens other lenses of arranging in pairs or groups, and contributes to increasing available aperture and reduces Fno.Second lens
